How to Put Out an Electrical Fire, or... Fight Fire With Fire?

It's certainly an established fact that electricity can cause fires, but today a group of Harvard scientists presented their research on the use of electricity for fighting fires. In a presentation at the 241st National Meeting & Exposition of the American Chemical Society, Dr. Ludovico Cademartiri told of how they used a unique device to shoot beams of electricity at an open flame over one foot tall. Almost immediately, he said, the flame was extinguished... Apparently, it has been known for over 200 years that electricity affects fire – it can cause flames to change in character, or even stop burning altogether. 

It turns out that soot particles within flames can easily become charged, and therefore can cause flames to lose stability when the local electrical fields are altered.

The Harvard device consists of a 600-watt amplifier hooked up to a wand-like probe, which is what delivers the electrical beams. The researchers believe that a much lower-powered amplifier should deliver similar results, which could allow the system to be worn as a backpack, by firefighters. It could also be mounted on ceilings, like current sprinkler systems, or be remotely-controlled. (more)

The Ray Gun is Back...

...and you're going to need more than a tin foil hat this time.

The ray gun has become more than a boyhood fantasy. The Army is quietly working to develop technology with the potential to arm tomorrow's armored combat vehicles with the capability to destroy electronic systems with high-intensity bursts of RF energy. (video)

"Tony! Missile at six o'clock!"

Raytheon engineers show Iron Man suit - The new robotic suit enables the wearer easily to lift 200lb several hundred times without tiring and repeatedly punch through three inches of wood; yet, the suit, which was developed for the U.S. Army, is also agile and graceful enough to let its wearer kick a football, punch a speed bag, or climb stairs and ramps with ease. 

They unveiled the second-generation exoskeleton called XOS 2 at the company’s research facility in Salt Lake City, Utah.

The new robotic suit is lighter, faster, and stronger than its predecessor, yet it uses 50 percent less power. Its enhanced design also means that it is more resistant to the environment. (more)

Laser Beam Eavesdropping - 2010

It is time to update our views on laser beam eavesdropping. While not entirely practical yet as an everyday amateur/business spy tool, advancements are being made which have us concerned.

Last year, researchers from Bar-Ilan University (Ramat-Gan, Israel) and the Universitat de València (Burjassot, Spain) developed a new way to sense sound remotely using a laser beam. Their paper is called: "Simultaneous remote extraction of multiple speech sources and heart beats from secondary speckles pattern" by Zeev Zalevsky, Yevgeny Beiderman, Israel Margalit, Shimshon Gingold, Mina Teicher, Vicente Mico, and Javier Garcia.

Unlike classic laser beam eavesdropping, the new method does not rely on interferometer or a reflecting diaphram, like a window. A single laser beam is aimed at the object to be monitored (a person and a cell phone were used in their tests). The speckles that appear in an out-of-focus image of the object are then tracked. This produces data from which a spectrogram or sound signal can be constructed.

The setup is basic. The laser illuminates a small area on the object and an ordinary digital camera captures the scene. The camera's lens is defocused. This produces a pattern that does not randomly change when the object moves. The camera image is processed, calculating the shift of the pattern from frame to frame. (more) 

Laser beam audio samples...

• Cell phone at 60m.

• Neck of person at 30m.

• Face at 100m.

• Heartbeat at 60m.
Note: Audio is labeled as they were in the paper. However, it sounds like the neck and face audio clips may have been reversed.

"Perfect place to use them in conference rooms and Churches."

"The worst place for me is the bank, you're standing there, waiting, quiet (I have my phone on vibrate usually) and phone nearby you rings and someone cusses and argues or talks about idle crap while everyone else has to stand around and listen? Or in a diverse place, you might get a loudmouth in Spansih, another in Mandarian, or someone giving an idiotic opinion that doesn't make sense and then me and people in line start discussing and bickering cause that's all we can DO!!! I want to JAM em so bad right then and there. Legal or not. ;)"

The Case of the Telepathic Ray Gun, or...

..."Does that ringing in my ears bother you?"
via Discovery.com
I know some of you may not want to believe this, but the U.S. government may well already have the ability to beam secret commands to you through the fillings in your teeth. Well, not exactly. But close. A recently declassified 1998 U.S. Army report, “Bioeffects of Selected Nonlethal Weapons,” describes government plans for a microwave weapon that would transmit voice communication that seems to emanate from within a human target’s own brain. (It was obtained and posted on the Web by Freedom From Covert Harassment & Surveillance, a Cincinnati-based organization that advocates on behalf of people who believe they are being stalked and subjected to “electromagnetic harassment.”)

To quote the report:
Because the frequency of the sound heard is dependent upon the pulse characteristics of the RF energy, it seems possible that this technology could be developed to the point where words could be transmitted to be heard like the spoken word, except that it could only be heard within a person’s head.

This is possible because of something called the Microwave Auditory Effect, which was first discovered during World War II, when people working in the vicinity of radar transponders complained of hearing strange clicking noises that other people nearby didn’t notice. The effect is caused by thermal expansion of the region around the cochlea. In the 1960s, neuroscientist Allan H. Frey, who was the first to publish research on the effect, was able to induce it in human subjects with pulsed microwaves from a transmitter 100 meters away.

It’s unclear just how far the government’s microwave auditory research and development efforts have progressed since 1993, when the report was written... (more)

"I reprogrammed a car fob, Mr. Cheney. Now I control you."

A team of respected security researchers known for their work hacking RFID radio chips have turned their attention to pacemakers and implantable cardiac defibrillators.

The researchers will present their paper, "Pacemakers and Implantable Cardiac Defibrillators: Software Radio Attacks and Zero-Power Defenses," during the "Attacks" session of the 2008 IEEE Symposium on Security and Privacy, one of the most prestigious conferences for the computer security field...

By reading between the lines (millions of remotely implanted medical devices, able to administer electrical shocks to the heart, can be controlled remotely from distances up to 5 feet, designed by people who know nothing about security), it is easy to predict the gigantic media storm that this paper will cause when the full details (and a YouTube video of a demo, no doubt) are made public.

Arthur C. Clark Predicts - E-Bomb in 2010

"Looking back on the appalling 21st century from our vantage point, 500 years later, it sometimes seems incredible that the human race could have survived such a time of troubles. The moment of greatest danger can now be pinpointed precisely--the year 2010.

Fifty years earlier, the chief threat seemed to be from thermonuclear weapons; however, these could be manufactured only by wealthy nations possessing both vast financial resources and a high level of technology.

Then, suddenly and totally unexpectedly, the situation was transformed by the invention of the Electromagnetic Pulse Bomb. The origin of this terrifying device is unknown: Like most concepts whose time has come, it was probably invented independently in a number of places. However, the first public account appeared in the September 2001 issue of Popular Mechanics under this dramatic headline:
E-BOMB: In the blink of an eye, electromagnetic bombs could throw civilization back 200 years. And terrorists can build them for $400." (more)

Laser Beam Eavesdropping

Laser beam eavesdropping...
Here is a subject that pops up every few years, grabs the press and public by the nostrils, hitches them to the paranoia pony and drags them around kicking and screaming with fear and delight.

We built an LBE to put client fears into perspective when the subject urped up in the 80's. You can read all about it here.

Another experimenter has published an admirable update here.

Movie versions about LBEs may be seen here and here.

Bottom line...
Technically, a lot of fun and very impressive ...in-the-lab.
Realistically, this is not an eavesdropping threat for most people. Relax.

How to remotely disable security cameras nondestructively from quite a distance…

Cell Phone Activated DIY CCTV Camera Blinding Project - from c-h-a-o-s.com

"It’s no secret. A lot of my inspiration comes from movies and for quite some time I have become more and more annoyed by Hollywood's sometimes rather silly solutions for an agent to shut down security cameras in order to remain undetected: e.g. blowing up the nearby power-plant or rigging up gadgets in sewers, where they can be detected by renovation workers and the sorts. If you blow something up or otherwise break it, your counterpart will immediately know it is sabotage and rule out a simple technical malfunction.

Another thing that got me to write this article is the abundant usage of surveillance cameras everywhere which makes me want to burst the bubble about security of surveillance cameras by exposing their weakness. Switching point of view will also often lead to improvement…" (more)
